What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Columbia, SC wrote its last area forecast discussion before this special weather statement went out at Jun 2, 10:30 PM EDT, 17 minutes earlier.

Area forecast discussion, Jun 2, 10:30 PM EDT, 17 minutes before
Area Forecast Discussion
National Weather Service Columbia SC
1030 PM EDT THU JUN 2 2016

.SYNOPSIS...
Moisture will circulate into the forecast area on the backside of
high pressure centered off the southeast coast and ahead of a cold
front slowly approaching from the west. The front will be in the
forecast area Monday and Tuesday. The deepest moisture will occur
ahead of the front Saturday Night and Sunday.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
Scattered convection lingering across portions of the forecast
area late this evening, mainly over the eastern Midlands. More
scattered convection in eastern GA approaching the CSRA. All
activity appears to be slowly weakening. Latest SPC HRRR
confirming that the convection should continue to slowly diminish
over the next hour or two. Locally heavy rain could still be a
threat as well with weak storm motion and efficient warm rain
processes.

Temperatures will be mild overnight as they are slow to cool with
convective debris clouds around through the first half of the
night and some lingering scattered mid level clouds through dawn
Friday. Overnight lows forecast to be in the upper 60s to around
70 degrees.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY/...
The models displayed surface ridging extending from the Atlantic
to just south of the forecast area. There was weak surface
troughing shown near or in the forecast area. Expect thunderstorms
mainly associated with strong heating, but h5 ridging should limit
coverage. The guidance consensus supported chance pops. The NAM
had moderate instability with surface-based lifted index values -6
to -7 plus an inverted-v forecast sounding. Strong wind gusts
will be possible with the thunderstorms. Recent verification and
the upper ridging favored the higher maximum temperature
guidance. The low temperature guidance was close.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Expect considerable shower and thunderstorm coverage Saturday
Night and Sunday. The models have been consistent showing a
moisture increase Saturday Night with high moisture continuing
through Sunday ahead of a slow moving cold front and developing
upper troughing. We leaned toward the higher guidance pops and
forecasted likely. The cold front should be in the forecast area
Monday and Tuesday but the models have been consistent showing
deeper moisture ahead of the upper trough east of the region.
Also, there has been consistency with developing low pressure
lifting northeastward from the Gulf staying well east of the
forecast area. Forecasted just chance pops. Further drying should
occur behind the front for Wednesday and Thursday. The GFS and
ECMWF MOS had the highest pops Sunday and Sunday Night with
values 40 to 60 percent. The MOS had pops 20 to 30 percent Monday
and Tuesday, and less than 20 percent Wednesday and Thursday. The
GFS ensemble mean pops were close but there was a high spread
Monday diminishing forecast confidence for that day. The MOS had
temperatures above normal ahead of the front through Saturday,
then near normal during the rest of the period.

&&

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
VFR conditions generally expected through the early portion of
tonight at all sites. Later tonight, possible mvfr/ifr visibility
restrictions developing at both ags/ogb. vfr conditions return at
all sites after 12z Friday.

Isolated showers and thunderstorms will continue to be possible
across the area over the next several hours as a weak shortwave
moves across the region. Will continue to monitor trends in and
around terminals, and will update later tonight if coverage nears
a taf site.

Winds generally variable around 5 knots due to current surface
outflow boundaries moving through the cwa. Winds will eventually
become light and variable to calm late tonight and into Friday.

Fog chances will be low early tonight, then increasing chance for
mvfr/ifr bf/fg development at ags/ogb after 09z through sunrise.
Remaining sites will be vfr.

EXTENDED AVIATION OUTLOOK...A cold front will approach the area over
the weekend bringing associated restrictions through the entire
weekend.
